Definitions
- the invention relates to a storage-stable bleach dispersion, which in addition to at least a peracid, a peracid-forming system or its salts, one or more optical brighteners of the bis-benzofuranyl type contains, as well as the production and use of these Bleach dispersion for simultaneous bleaching and lightening of fabrics in the Household and in industry, at temperatures from + 10 ° C or higher.
- the invention thus relates to an aqueous storage-stable bleaching agent dispersion containing 2 to 70% by weight, based on the total weight of the formulation, one or more peracids, peracid-forming systems or their salts, and 0.01 to 1% by weight of an optical brightener or a mixture of optical brighteners, characterized in that the optical brighteners are bis-benzofuranyl brighteners of the formula (1) are in which R 1 and R 2 are independently hydrogen, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, halogen, benzyloxy or phenoxy, R 3 C 1 -C 4 alkyl, halogen or phenyl, M hydrogen or an equivalent of a non-chromophoric cation and n is 1 to 4; that hydrogen peroxide, diperoxyalkyl dicarboxylic acids, phthaloamino peracids or sulfonyl pers acids are used as peracids; and that as peracid-
- C 1 -C 4 alkyl and C 1 -C 4 alkoxy are methyl, ethyl, butyl and tert-butyl as well as methoxy, ethoxy and butoxy.
- sodium and potassium are preferred for the alkali metal ions.
- R 1 is hydrogen, methyl or methoxy and R 3 is methyl, ethyl or phenyl, the optical brighteners of the formulas (3), (4) and (5) is of particular importance.
- the optical brightener content is 0.01 to 1% by weight, preferably 0.05 to 0.25 % By weight, based on the total weight of the formulation.
- optical brighteners of formulas (1) to (5) are known and can e.g. according to EP-A-395 588.
- the peracids present in the bleach dispersions, peracid-generating systems or their salts are in an amount of 2 to 70 wt.% And preferably in an amount of 5 to 40% by weight, based on the total weight of the Formulation, added.
- Hydrogen peroxide comes into question as inorganic peracids.
- Hydrogen peroxide and diperoxyalkyldicarboxylic acids such as that are preferred Diperoxydodecanedicarboxylic acid, or a mixture thereof.
- Tetraacetylethylenediarnin TAED
- NOBS Nonoyloxybenzenesulfonate
- i-NOBS iso-nonoyloxybenzenesulfonate
- Sulfonate phenyl benzoates can be used.
- a catalyst or one Catalyst mixture can be added.
- Suitable catalysts are, for example, transition metal compounds such as copper, cobalt and manganese compounds. Examples include CuSO 4 , cobalt-amine complexes or manganese complexes with multidentate ligands.
- Suitable sulfonates are, for example, water-soluble salts of alkylphenyl sulfonates, paraffin sulfonates, ⁇ -olefin sulfonates, fatty acid monoglycerol sulfonates, 2-acyloxy-alkane-1-sulfonates and ⁇ -alkyloxy-alkane sulfonates, as mentioned in GB-A-2 141 754.
- Examples include sodium pentadecyl sulfonate or dioctyl sulfosuccinate, and especially the C 9 -C 15 alkylphenyl sulfonates.
- nonionic surfactants are compounds which are characterized by the Condensation of ethylene oxide, propylene oxide or a mixture of both with one Hydrocarbon bearing an active hydrogen atom is formed.
- alkyl or alkylene, mono- or polyglucosides are suitable. These preferably have alkyl or alkylene groups with 9 to 15 carbon atoms and 1-10 glucoside units. Examples include nonyldiglucoside and allyl (C 12 -C 15 ) poly (1-10) glucoside. Sorbitan esters such as polyoxyethylene sorbitan monopalmitate, fatty acid ethanolamides such as coconut fatty acid diethanolamide and fatty acid ethanolamine oxides such as tetradecylamine oxide can also be used.
- Saturated and unsaturated carboxylic acids such as e.g. Oil, caprine, Lauric, myristic, coconut, palm kernel acid or salts thereof, e.g. the sodium, Potassium or ammonium salts are used, the coconut fatty acid derivatives are particularly preferred.
- Examples of the group of phosphonates and polyphosphonates are e.g. Aminotrimethylphosphonic acid, Aminotriethylphosphonic acid, ethylenediaminetetramethylphosphonic acid and diethylenediaminetetramethylphosphonic acid and compounds such as they are described in US-A4 321 165.
- additives such as further surfactants, Emulsifiers, thickeners, foam regulators, stabilizers, odor improvers, Sequestering agents, salts or dyes.
- the bleach dispersion is produced by using the optical brightener (s) as a moist press cake or dry powder with one or more peracids or peracid-forming systems together with water and possibly other additives mixed and homogenized.
- the bleach dispersion thus obtained is for months stable and does not sediment.
- the optical brightener can be incorporated without visible sedimentation and its After neutralizing the oxidizing agent with hydrosulfite, the amount is determined spectroscopically to 100% of the amount used. The dispersion obtained is stable.
- the bleach dispersions according to Examples 1 and 2 are at 14 days stored at a temperature of 20 ° C in the dark. When determining the Optical brightener content in both cases results in a content of 100% of the Baseline.
- the optical brightener content is 85% after 3 days at 26 ° C Output quantity.
